rl`his invention `relates tofeed grinders,

and it consists in the novel features herein after `described vand claimed. Y

An object of the invention is togprovide afeed grinder which may be readilyconnected with a feeder, and whichl may be used to advantage for grinding corn fodder,

alfalfa hay, cane, millet, lrar corn, and similar feed.

A. further object of the invention is t0.y lprovide in a grinder of the character stated,

i comprises a supporting frame upon which is mounted a casing. A shake-up pan is mounted in the casing and the conveyor is.

arranged to move over the said pan, Feeders are adapted to receive the material from the conveyor and move the material over the edge of the pan and present the same to feeders, some of which are housed under a hood, which is disposed above the mill. After being treated in the mill, the material passes through a. screen and is conveyed away from the mill by an elevator, which 1s mounted upon the frame.

In the accompanying drawing: Y Figure 1 is an elevation of the feed grinder looking at one side thereof. y Y e Figure 2 is an elevation of the feed grinder looking at the opposite side thereof.

Figure 3 is a fragmentary diagrammatic view of the grinder. Y

i Figure 4 is a side elevation of the beater used in the grinder.

Figure 5 is a transverse sectionalview of the beater, shown in Figure 4. v

As illustrated in the accompanying drawing, the feed grinder comprises a frame 1, upon which a master shaft 2, is ]ournalled for rotation. Collars 3 are mounted upon the ends of the shaft 2, and a pulley 4 may be provided upon the intermediate portion' of the said shaft, and around which a. belt (not shown) may be trained, for the purpose of transmitting rotary movement to the said shaft 2.

A casing 5 is mounted upon the frame 1, and a cylinder 6 is journalled in the casing 5. A concaved screen 7 is loca-ted in the casing 5 below the cylinder 6. A hood 8 is disposed over the end of the casing 5 and is spaced above cylinder 6. The hood 8 is provided at its upper portion with a depend` l ingapron Feeders lOand 11 vare .journalled under thehood 8, and above the cylinder` 6. A *pan 12 is .located below the ylower edge of theapron 9, and a beater 13 is journalled above the pan 12. A convevor 14 is located above the vpan 12, and a feeder roll 15 is journalled. about the delivery end of the conveyor 14. An elevator andk conveyor 16 is mounted uponv the frame 1, with its receivingend below the screen 7.

A belt 17 is trained'around oneof the puly leys3 and around a pulley `13 mounted upon a shaft'of the cylinder" 6.y A shaft 19 is journalled upon the frame 1, and carries a pulley 20. lA beltv 21 is trained around the pulley and a pulley 22 mounted upon the Vshaft 2. A sprocket chain 23 is operatively connected with the shaft 19, and with the active elements of the conveyor and elevator 16. The shafts of the feeders 10 and 11 are connected together at one side ofthe casing by a sprocket chain 24. A belt 25 operatively connects the shaft 19 with one .of the beater shafts and serves as means for transmitting rotary movement from the shaft 19 y to thebeaters 1() and 11. A shaft 26 is journa-lled at the intermediate portion of the frame 1, and a pulley 27 is mounted thereon. A belt 28 is trained around the pulley 27 and one of the pulleys 3 carried by the shaft 2. An idler pulley 29 is jourj nalled at the side of the casing ofthe appa ratus and bears against ythe under surface of the upper run of the belt 28, as best shown in Figure 2 of the drawings. A pulley 30 is also mounted upon the shaft 26. A pulley 31 is mounted'upon the feeder shaft. A pulley 32 is mounted upon the-shaft of a feeder roll' 33 which is mounted above the feeder 13 and a belt 34 is trained around the pulleys 30,31 and 32, and is adapted to transmit rotary movement from the shaft 26 to the feeders. A sprocket chain 35 op- I vA sprocket chain 38 is trained aroundathe sprocket wheels'36 and 37 and is adapted to transmit movement from` the beater 15 to the conveyor 14.V l

The feed is carried by the conveyor under the feeder 15, which moves the same over the pan 12 and under the beater 33. The i feeder forces the material under the feeder i3, and the material is subjected to the action of the said beater. From the said beater, the material is passed4 under the apron 9 of the hood 8, and under the beaters ll and l0. The last mentioned beaters pass the iieed down toward and upon the cylinder 6, where the material is ground and passed through the screen 7. From the screen 7, the material falls upon the elevator and conveyor l@ and is moved beyond the end of the frame l.

The cylinder 6 is of usualform and such as is generally employed in an alfalfa mill for breaking the material into particles. As

. the material passes over the pan 12 and the top of the cylinder 6 it is compacted and partially broken Yby the beater' 18 and the feed ers ll andlO. The material in this condition is carried by the cylinder 6 and is forced through the openingsin the screen 7 and in so doing is reduced to particles or bits. The

screen, a cylinder journaled for rotation above the screen, a hooddisposed over the cylinder and screen and having a material receiving opening, said'hood having at the upper sideot said opening, an inwardly dis posed concave apron, the lower edge ot which is spaced above the cylinder, a beater lo cated exteriorly ol the hood and opposite the apron and above the lower edge thereof, a beater located under the hood andvetically above the center oi the cylinder, and a third beater located under the hood andA at the side ofthe secondy mentioned beater and above the side portionV of the cylinder.
